brutal bro, i really like the idea but i think that maybe just one good dominant would be enough.. not everyone plays nj and as you saw at t1 nationals 2015, not everyone even plays Son of God
sacrificing 1 dom for another is a huge cost, so i think the benefit is justified. it's not terribly op, but keep in mind that one dom costing another basically puts you at 6 doms in a 50 card deck so..
well done, really digging your card ideas you are coming up with keep'em rolling! you'll see your ideas become printed in no time..
